Project Background


This project widened Issaquah Fall City Road to four lanes, between 242nd Ave SE and Klahanie Dr SE. The additional lanes along with roundabouts at 242nd, 247th, and Klahanie Drive will improve traffic flow and reduce commute times on this highly-congested roadway. 

Goals and Benefits

As part of the newly annexed section of the City (January 1, 2016), SE Issaquah-Fall City Road is a vital connection route to residents of the City of Sammamish and surrounding communities. This project will double the existing two-lane section to a four-lane section.

It promotes the City’s goal of complete streets by including bike lanes, sidewalks, landscaping, and a protected student crossing at Pacific Cascade Middle School.

A bridge located between 247th and Klahanie Drive will raise the roadway to improve safety and meet federal driver stopping sight distance requirements. North Fork Issaquah Creek will be removed from a culvert underneath the roadway into a stream channel spanned by the bridge.

The 100% design plans, specs, and estimate have been delivered. All permits have been attained. Projected August 2019 construction start date.
